According to the leaking stoppage device of the hot-blast furnace foundation, the plugging plate is arranged at the gap between the reinforcing ribs of the foundation bolts of the hot-blast furnace foundation in a solidifying mode, so that the foundation bolt reinforcing ribs surrounding the periphery of a furnace shell of a hot-blast furnace and the plugging plate are connected into an integral cavity, the grouting holes are evenly distributed in the plugging plate, an external grouting method is used for plugging air leakage of the furnace foundation, the investment is saved, an original structure is not damaged, the working stability of the hot-blast furnace can be effectively maintained, and construction personal safety is facilitated. The leaking stoppage device of the hot-blast furnace foundation is simple in structure, short in days for construction, good in safety, and capable of effectively strengthening the furnace foundation, plugging air leakage of the furnace foundation and protecting the furnace shell, thereby prolonging the service life of equipment.
Description
Technical field
The utility model relates to a kind of metallurgical mining technique field, be specifically related to a kind of simple in structure, stable performance, easy to operate hot-blast stove furnace foundation device for plugging.
Background technology
Hot-blast stove is mainly comprised of a large amount of refractory masonries and ancillary service, has sizable loading.This just requires hot-blast stove must have corresponding basis, and this basis, is called furnace foundation.The furnace shell of modern high temperature hot-blast furnace is together with drop-bottom, to be welded into a gastight integral body with the hot-blast stove steel plate that 8～20mm thickness does not wait, and portion serves as a contrast with refractory masonry within it, and with fang bolt, furnace shell is fixed on furnace foundation.Furnace foundation can bear whole loadings, and keeps hot-blast stove stable.Prior art top combustion stove, due to the grout hole of offering on furnace shell base plate in hot-blast stove foundation construction process after grouting during shutoff due to construction Welding Problems, after causing going into operation, hot-blast stove furnace foundation around leaks out, hot-blast stove runout damage furnace shell, reduces service life of equipment and jeopardizes operating personnel's personal safety.For this reason, develop a kind of simple in structure, effectively reinforce furnace foundation, shutoff furnace foundation leaks out, and protection furnace shell, guarantees that the hot-blast stove furnace foundation device for plugging of construction safety is the effective way addressing this problem.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and shutoff furnace foundation leaks out, and keeps hot-blast stove working stability be conducive to the to construct hot-blast stove furnace foundation device for plugging of personal safety.
The purpose of this utility model is achieved in that and comprises that plugging plate and grout hole, described plugging plate are arranged between the reinforcing rib of furnace foundation stone bolt, and described grout hole is uniform to be arranged among plugging plate.
The utility model is at the hot-blast stove fixed plugging plate that arranges of the gap location between foot bolt reinforcing rib fundamentally, make to be linked to be a whole cavity around the stone bolt reinforcing rib of hot-air stove shell periphery and plugging plate, and on plugging plate the uniform grout hole that arranges, adopt outside grouting shutoff furnace foundation to leak out, reduced investment, do not destroy original structure, effectively keep hot-blast stove working stability and be conducive to the personal safety of constructing.The utility model is simple in structure, the duration is short, safety is good, effectively reinforce furnace foundation, and shutoff furnace foundation leaks out and protects furnace shell, and then has extended the application life of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the utility model overall structure is overlooked cross-sectional schematic;
In figure: 1-plugging plate, 2-grout hole, 3-annular slab, 4-reinforcing rib, 5-drop-bottom, 6-furnace foundation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but must not to the utility model, be limited by any way, any change or the improvement based on the utility model training centre, done, all belong to protection domain of the present utility model.
As shown in accompanying drawing 1 ~ 2, the utility model comprises plugging plate 1 and grout hole 2, and described plugging plate 1 is arranged between the reinforcing rib 4 of stone bolt of furnace foundation 6, and described grout hole 2 is uniform to be arranged among plugging plate 1.
Described plugging plate 1 is rectangular configuration, be tightly connected annular slab 3 lower planes of body of heater of its upper limb, its lower edge plane on drop-bottom 5 that is tightly connected.
Between two reinforcing ribs 4 of the width dimensions of described plugging plate 1 and stone bolt, distance adapts.
The cross section of described reinforcing rib 4 is for falling " U " shape structure, and two openends are fixed connection plugging plate 1 respectively.
Described reinforcing rib 4 they " U " shape mouths connect plugging plate 1 from beginning to end, form sealed cavity body structure with annular slab 3, the drop-bottom 5 of top and bottom.
Described grout hole 2 bore size are ￠ 30 ~ 50mm.
On described grout hole 2, orifice tube is set, the fixed grouting valve that arranges in described orifice tube outer end.
Described grout hole 2 end peripheries are filled up Anchor Agent and geotextiles mixed coating are set.
Operating principle of the present utility model and the course of work are as follows:
The utility model is at the hot-blast stove fixed plugging plate that arranges of the gap location between foot bolt reinforcing rib fundamentally, make to be linked to be a whole cavity around the stone bolt reinforcing rib of hot-air stove shell periphery and plugging plate, and on plugging plate the uniform grout hole that arranges, adopt outside grouting shutoff furnace foundation to leak out, reduced investment, do not destroy original structure, effectively keep hot-blast stove working stability and be conducive to the personal safety of constructing.
Yi Kungang new district 3# hot-blast stove furnace foundation around leaks out below, to furnace foundation grouting leak-stopping, is embodiment, further illustrates:
Adopt the steel plate of 10mm, according to hot-blast stove, process Plate Welding plugging plate in scene, the gap between foot bolt reinforcing rib fundamentally, make to be linked to be before a whole cavity is constructed and to need to clean out the foreign material between furnace shell and furnace foundation base plate angle together with annular slab, drop-bottom around the gap between the stone bolt reinforcing rib of hot-blast stove furnace foundation.Uniformly on the plugging plate of a week grout hole of four DN40 is set and loads onto valve being linked to be.Grouting adopts resin polymerization agent high fluidity grouting material, and first toward the grout hole grouting of a direction, other three grout hole valve opens, just can close this valve after seeing which hole pulp.After valve Close All, proceed back-grouting, and observe grouting machine outlet pressure, pressure starts pressurize after getting to suitable requirement, then changes another one grouting mouth until be in the milk.Adopt this outside grouting to block and leak out, reduced investment, do not destroy original structure.
The utlity model has simple in structure, the duration is short, safety is good, effectively reinforce furnace foundation, shutoff furnace foundation leaks out and protects furnace shell, and then the feature in extension device application life.
